Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 26 points:

(1,2);(3,4)(5,8)(6,7)(9,10)(11,12)(13,17)(14,15)(16,18)(19,20)(21,24)(22,23)(25,26);(4,7)(8,10)(12,15)(13,18)(20,22)(21,25);(11,12,14,15)(13,16,18,17)(19,21,23,25)(20,24,22,26);(3,4)(5,8)(6,7)(9,10)(11,12)(13,16)(14,15)(17,18)(19,21)(20,24)(22,26)(23,25);(3,5,6,9)(4,8,7,10)(11,13)(12,16)(14,18)(15,17)(19,22,23,20)(21,26,25,24)
